Definitions

  • the present invention is directed to mobile communication devices that perform simultaneous unicast transmission and reception and, specifically, to minimizing conflicts caused by simultaneous unicast and broadcast transmission and reception.
  • FIG. 1 provides an overview of a UMTS network.
  • the UMTS network includes a mobile terminal or user equipment (UE) 1, a UTRAN 2 and a core network (CN) 3.
  • UE mobile terminal or user equipment
  • UTRAN 2 a UTRAN 2
  • CN core network
  • the UTRAN 2 includes several radio network controllers (RNCs) 4 and NodeBs 5 that are connected via the I interface. Each RNC 4 controls several NodeBs 5. Each ub
  • RNC 4 handles the assignment and management of radio resources and operates as an access point with respect to the CN 3.
  • the NodeBs 5 receive information sent by the physical layer of the UE 1 via an uplink and transmit data to the UE 1 via a downlink.
  • the Node-Bs 5 operate as access points of the UTRAN 2 for the UE 1.
  • the SGSN 7 is connected to the equipment identity register (EIR) 8 via the Gf interface, to the MSC 6 via the G interface, to the gateway GPRS support node
  • EIR equipment identity register
  • the U-plane is a region that handles traffic information with the user, such as voice or Internet protocol (IP) packets.
  • the C-plane is a region that handles control information for an interface with a network as well as maintenance and management of a call.
  • One example of a mechanism for the transmission of a status PDU is the reception of a PDU with a sequence number that does not correspond to the latest received sequence number increased by one or when the receiver receives an indication from the transmitter in the RLC control information that an acknowledgment, or "status," should be sent.
  • the transmitter indication to send a status PDU is called "polling.”
  • the UTRAN 2 can determine the existence of a particular UE 1 within the unit of cells because an RRC connection exists for UEs in RRC connected mode. For example, the UTRAN 2 can determine in which cell or set of cells the RRC connected mode UE 1 is located and to which physical channel the UE 1 is listening. Therefore, the UE 1 can be effectively controlled.
  • the UTRAN 2 cannot determine the existence of a UE 1 in idle mode.
  • a UE 1 in CELL_DCH state will try to listen to DCH-type transport channels among others.
  • DCH type transport channels include DTCH and DCCH transport channels, which can be mapped to a certain DPCH, DPDSCH, or other physical channels.
  • a UE 1 in CELL_FACH state will listen to several FACH transport channels that are mapped to a certain S-CCPCH.
  • a UE 1 in PCH state will listen to the PICH channel and the PCH channel that is mapped to a certain S-CCPCH physical channel.
  • the main system information is sent on the BCCH logical channel, which is mapped on the primary common control physical channel (P-CCPCH). Specific system information blocks can be sent on the FACH channel.
  • the UE 1 receives the configuration of the FACH either on the BCCH that is received on P-CCPCH or on a dedicated channel when the system information is sent on FACH.
  • the P-CCPCH is always sent using the same scrambling code used by the primary common pilot channel (P-CPICH), which is the primary scrambling code of the cell.
  • P-CPICH primary common pilot channel
  • the spreading code used by the P-CCPCH is always number 1 and has a fixed spreading factor (SF) of 256.
  • the MIB also contains information on the last version of a part of the SIBs for SIBs that are linked to a value tag.
  • SIBs linked to a value tag are valid only if they have the same value tag as the SIB broadcast in the MIB.
  • SIBs that are not linked to a value tag are linked to an expiration timer and are invalid and must be re-read if the elapsed time since last reading the SIB exceeds this timer value.
  • a function called counting has been introduced in MBMS in order to allow the use of cell resources in an optimized manner.
  • a counting procedure as illustrated in FIG. 7, is used to determine how many UEs 1 are interested in receiving a given service.
  • FIG. 7 illustrates the general principle of a counting procedure.
  • a UE 1 will inform the RNC 4 that it is interested in a given service by sending a
  • a UE 1 camping on one frequency might not be aware of an MBMS service transmitted on a different frequency when a network operates on several frequencies.
  • a frequency convergence procedure allows a UE 1 to receive information on a first frequency that indicates a given service is available on a second frequency.
  • the MBMS point-to-multipoint Control Channel (MCCH) is used for a P-T-M downlink transmission of C-plane information between a RNC 4 and UEs 1 in RRC Connected or Idle Mode.
  • the C-plane information on MCCH is MBMS specific and is sent to UEs 1 in a cell with an activated MBMS service.
  • MCCH can be sent in S- CCPCH carrying the DCCH of the UEs in CELL_FACH state, in stand alone S- CCPCH, or in the same S-CCPCH with MTCH.
  • One MSCH is sent in each S-CCPCH carrying the MTCH.
  • the MSCH is always mapped to one specific FACH in the S-CCPCH, as indicated on the MCCH.
  • the MSCH is mapped to a different FACH than MTCH due to different error requirements.
  • UM-RLC mode is used for MTCH mapped to FACH, with required enhancements to support selective combining.
  • Quick repeat may be used in RLC-UM.
  • a MAC header is used for logical channel type identification and MBMS service identification.
  • UM-RLC mode is used for MSCH mapped to FACH.
  • a MAC header is used for logical channel type identification.
  • MBMS notification utilizes a new MBMS specific PICH in a cell, specifically MBMS notification indicator channel (MICH).
  • MICH MBMS notification indicator channel
  • FIG. 10 illustrates the schedule with which the MBMS SERVICE INFORMATION and RADIO BEARER INFORMATION is transmitted. Different shading in FIG. 10 indicates potentially different MCCH content.
  • the determination of the best cell / frequency / technology is similar to when the UE 1 is in idle mode or not connected to the network. Additional or new rules could be provided to the UE 1 in order to account for the choice of the technology / frequency band when the UE receives an MBMS or broadcast frequency (Sl 10).

Abstract

Cette invention concerne des procédés et un dispositif permettant de réduire les conflits provoqués par une réception/transmission à diffusion individuelle et à diffusion générale dans un dispositif de communication mobile. Le dispositif de communication mobile sélectionne une technologie pour la réception d'un service à diffusion individuelle/à diffusion multiple/à diffusion générale puis il désactive l'utilisation de technologies spécifiques ou l'utilisation d'une technologie spécifique sur une bande de fréquence spécifique susceptibles de gêner la réception d'un autre service.
